Collaborative Research: Google Earth for Onsite and Distance Education (GEODE)

这一合作项目是在先前工作的基础上，根据谷歌地球虚拟地球仪的功能，扩大、增加和传播地球科学学习资源。该项目的组成部分包括：1）开发一套全球分布的交互式虚拟实地考察，为谷歌地球基地添加高分辨率的千兆像素全景图像、虚拟露头和标本，以及自动分级，2）使用地球引擎API将大型地球科学数据集集成到虚拟地球仪中，从而实现其他形式的基于探究的学习和本科生研究，3）扩展工具包，包括移动的应用程序，以使更广泛的教师和学生能够向在线存储库贡献众包数据和教育资源，4）进行面对面和在线教师专业发展研讨会以促进使用，以及5）通过调查、点击流数据和预/后测试的组合评估传播工作和学生学习成果。这个项目的智力价值在于它能够利用用户友好，尖端的虚拟地球和千兆像素成像技术，让学生参与一系列的学习活动和虚拟环境。评估是通过调查和前后测试与更连续的点击流数据相结合的离散数据收集，以提供学生如何在这种虚拟环境中学习的见解。该项目的更广泛的影响包括：1）其在广泛的机构的适用性，既作为正式的课程作业，并在本科地球科学课程内外的辅助使用，2）广泛的教师专业发展，使用面对面，网络研讨会和小组视频会议的方法，3）材料开发专门为职前科学教师，以及4）为行动不便的学生以及那些因工作或家庭原因而限制参加实际实地考察的学生提供通道。

This collaborative project builds on prior work to expand, augment and disseminate geoscience learning resources based on the affordances of the Google Earth virtual globe. Components of the project include 1) development of a suite of globally distributed interactive virtual fields trips which add high-resolution gigapixel panoramic images, virtual outcrops and specimens, and automated grading to the Google Earth base, 2) using the Earth Engine API to integrate large geoscience datasets into the virtual globe, enabling additional forms of inquiry-based learning and undergraduate research, 3) expanding toolkits, including mobile apps, to enable a broader range of faculty and students to contribute crowd-sourced data and educational resources to an online repository, 4) conducting face-to-face and online faculty professional-development workshops to promote use, and 5) assessing dissemination efforts and student learning gains through a combination of surveys, clickstream data and pre-/post-tests. The intellectual merit of this project lies in its ability to leverage user-friendly, cutting-edge virtual-globe and gigapixel-imaging technology to engage students in an array of learning activities and virtual settings. Assessment is combining discrete collection of data through surveys and pre- and post-tests with more-continuous clickstream data to provide insights into how students learn in such virtual environments. The broader impacts of the project include 1) its applicability across a wide range of institutions, both as formal course assignments and for ancillary use in and beyond the undergraduate geoscience curriculum, 2) extensive faculty professional development using face-to-face, webinar and group-video-conferencing approaches, 3) materials development specifically for pre-service science teachers, and 4) provision of access for mobility-impaired students, as well as those with work or family commitments which limit participation in actual field trips.
